Associated Launch Sites

Atlantic Ocean Sounding rocket launches made from naval vessels in the Atlantic accounted for 521 launches from 1947 to 1995, reaching up to 750 kilometers altitude. More...

Cape Canaveral America's largest launch center, used for all manned launches. Today only six of the 40 launch complexes built here remain in use. Located at or near Cape Canaveral are the Kennedy Space Center on Merritt Island, used by NASA for Saturn V and Space Shuttle launches; Patrick AFB on Cape Canaveral itself, operated the US Department of Defense and handling most other launches; the commercial Spaceport Florida; the air-launched launch vehicle and missile Drop Zone off Mayport, Florida, located at 29.00 N 79.00 W, and an offshore submarine-launched ballistic missile launch area. All of these take advantage of the extensive down-range tracking facilities that once extended from the Cape, through the Caribbean, South Atlantic, and to South Africa and the Indian Ocean. More...

San Clemente Military facility on the California Channel Islands, used for rocket launches in support of other missile tests from Vandenberg or Point Mugu. In use from 1957. Known to have been used for 10 launches from 1958 to 1984, reaching up to 672 kilometers altitude. Later plans were made for an off-shore launch platform here for the Starstruck vehicle. More...

Cape Canaveral LC3 X-17, V-2, Polaris, Bomarc launch complex. This complex was built to support the Bomarc interceptor missile program, but also supported Bumper, Jason, Redstone, X-17 and Polaris ballistic missile operations. The Air Force accepted Complex 3 in November 1951. The location had already supported the Cape's first major launch - Bumper 8 - on 24 July 1950. Following the last Bomarc launch in April 1960, some Bomarc support facilities were converted into a medical support area for Project Mercury. Later the complex supported tethered aerostat programs from 1983 through 1989. More...

Cape Canaveral LC25A X-17, Polaris launch complex. Complex 25 was built to support the U.S. Navy's Polaris submarine ballistic missile program. The Navy occupied pad 25A in December 1957. Complex 25 supported 68 Polaris missile launches between 18 April 1958 and 6 March 1965. Pads 25A and 25B were dismantled in September 1969. More...

NACA research on reentry configurations. - .
Nation: USA. Personnel of NACA Langley and Ames Aeronautical Laboratories were engaged in research on aerodynamic characteristics of reentry configurations. Knowledge acquired from these efforts along with those of industry and the military services was used in Project Mercury, proved the ablation theory for the Army's Jupiter missile development program, and was used in the Air Force intercontinental ballistic missile nose cone reentry program.

Argus I Nuclear test - .
Nation: USA. Agency: USN. Apogee: 160 km (90 mi). The Argus series were the only clandestine nuclear tests ever conducted by the United States. The rocket-launched nuclear warheads were set off at very high altitudes over the South Atlantic, 1800 km south-west of Capetown, South Africa. The purpose was to determine the effects of nuclear explosions on the Earth's magnetic field and the impact to military radar, communications, satellites and ballistic missiles electronics. The earth's magnetic field is not only off-axis from the earth, but also off centre from the earth's core. This means the Van Allen Radiation belts are closest to the earth in the region known as the 'South Atlantic Anomaly'. This made the selected launch point the ideal place for launching a rocket into the lower belt where the particles and radiation from the explosion would be trapped.

The 1.7 kiloton W-25 warhead used had been developed and previously tested for the Genie air-to-air missile. The first test was launched from vessel AVM1 at 38.5 deg S, 11.5 deg. W, and exploded at an altitude of 160 km. The initial flash was followed by an auroral luminescence extending upward and downward along the magnetic lines where the burst occurred. The experiment verified the predicitons made in the original October 1957 proposal by N. C. Christofilos of the Lawrence Radiation Laboratory in Livermore.
